I guess for a thesis research, it would be expected of you to do google searches for general articles, so a more specific question/request is more likely to get answers. But to get you started:
Since it's implemented in chromium open source project you can find some of the relevant code sections here:
The top folder for the sdch in chromium source:
How the dictionary is fetched at the browser:
The algorithm used:
Google scholar is also a good resource to search for research material. The following should list the
The google design document for sdch (I got this link from this google group itself)
PS: I have close to zero knowledge of sdch, chanced on this group and some of the links today while googling for something else. You should route all detailed questions to either chromium/google developers working on sdch currently or other people in this google group.
All the best for your thesis work.
